Photoshop: Multi-monitor panel behavior in OS X 10.9...

Just upgraded to Mavericks. I used a two-monitor setup and I keep several PS panels open on my right-side monitor with my main work area on the left-side monitor. Before Mavericks the panels would stay on the right monitor even when switching between apps, "Spaces" or different desktops. Now with Mavericks, every time I switch away from PS and switch back, or switch between desktops, the panels jump back over to the left-side monitor. If I "reset" my workspace they hop back over to the right-side monitor where they belong but this is annoying me to death having to do that every time I switch back and forth between apps/desktops!

Thanks for the response(s) Chris. I'm guessing you just mean this suggestion as a short-term fix, but turning off features, IMHO, is not a very good solution. I keep all of my productivity apps on different desktops and keep them assigned so I always know what is where.

Josh, it turns out you can put Adobe panels and windows on another monitor in Mavericks by changing a setting. Go to System Preferences, click Mission Control, and turn off "Displays have separate Spaces." This will preserve the multi-monitor setup when you switch out of and back to an Adobe app.

This will also let you stretch a single window across two monitors, which isn't possible when that option is on.

That does not necessarily mean this is as designed, or a bug by either Apple or Adobe, but the Adobe staff who already answered will figure that out.

(FYI Chris, I had not assigned Photoshop to a specific space when I tried it out.)

Thanks for the reply Conrad - I figured the "glitch" would be remedied by turning off the new feature of independent Spaces, however I love this feature so it's a huge tradeoff. I've been waiting for independent monitor control for years...

Exactly the same for me, not sure if its a 10.9 issue rather than Adobe, I assume the ether will be hot along the Pacific Coast to try and find a solution. I note that it does try to keep most of the panels on the second monitor with a workaround, change workspace to another then back to the desired one, I note my Nik panel keeps returning to the main monitor screen usually along with another mostly brushes.

Yes if you change workspace, or just refresh current workspace, the panels pop right back to where they should be, which tells me there may be an easy fix for Adobe to just add some code to reset panels when switching back from another app and/or desktop space.

This doesn't sound like something Adobe can do. Photoshop already puts the panels and dialogs back in place, UNLESS the OS tells Photoshop that the other displays are no longer available. In this case Spaces is telling Photoshop that the other display is not available, and everything has to be moved back to the main display.
You can work around this by changing your settings in Spaces, or it is something that Apple will need to fix.
